In this respect, they exactly resemble the Florida Cormorant. There are facts connected with the habits of birds which might afford a pretty good idea of the relative temperatures of different parts of the country during a given season; and those observed with regard to the Anhinga seem to me peculiarly illustrative of this circumstance. I have found the “Grecian Lady” breeding on St John’s River in East Florida, near Lake George, as early as the 23d of February; having previously seen many of them caressing each other on the waters, and again carrying sticks, fresh twigs, and other matters, to form their nests, and having also shot females with the eggs largely developed. Now, at the same period, perhaps not a single Anhinga is to be seen in the neighbourhood of Natchez, only a few about New Orleans, in the eastern parts of Georgia, and the middle maritime portions of South Carolina. In Louisiana this bird breeds in April or May, and in South Carolina rarely before June, my friend BACHMAN having found eggs, and young just hatched, as late as the 28th of that month. In North Carolina, where only a few pairs breed, it is later by a fortnight. I have already expressed my opinion that birds which thus breed so much earlier in one section of the country than in another, especially when at great distances, may, after producing one or even two broods, in the same year, still have time enough to proceed toward higher latitudes for the purpose of again breeding. Actual observations have moreover satisfied me that individuals of the same species produced in warm latitudes have a stronger disposition toward reproduction than those of more northern climates. This being the case, and most birds endowed with the power of migrating, having a tendency to exercise it, may we not suppose that the pair of Anhingas which bred on the St John’s in February, might be inclined to breed again either in South Carolina or in the neighbourhood of Natchez, several months after. But, as yet, I have not been able to adduce positive proof of the accuracy of this opinion.
